The University of Cincinnati hosts an interesting site on Troy.
It has been created in collaboration with the Troja-Projekt at the University of Tübingen and the CERHAS of the University of Cincinnati. You find there a wealth of material on the current state of research about Troy, with historical timelines, information about the Trojan myths and tables explaining the structure of the Iliad within the Trojan cycle.
Among the many maps you find there, you may also come across some 3D reconstructions. They represent either views on parts of the city or show the aspect the city may have had during the different periods in short films.
